Gypsum Retarder (Liquid)
Guudpoly Liquid gypsum retarder is a water-borne, vegetable protein-based, high-efficiency additive designed to precisely delay the setting time of gypsum boards with minimizing effect to their final strength. serving as a sustainable alternative to animal protein and synthetic retarders.
Related Product & Application
Vegetable Protein vs Animal Protein
Sustainability & ethics: – Plant sources are renewable, cruelty-free, and have lower carbon footprint; animal protein relies on slaughterhouse by-products.
Consistency & odor: – Vegetable protein has uniform peptide chains, no putrid odor, and better batch-to-batch stability; animal protein may vary in quality and smell.
Safety & hygiene: – Lower risk of pathogens or contaminants; ideal for food-contact or indoor-sensitive applications.
Stable supply: – Plant raw materials are more abundant globally.
🌱 Core Advantages
Renewable & eco-friendly: –Derived from abundant plant sources; formaldehyde-free, non-toxic, biodegradable, and compliant with green building standards.
Very High efficient & controllable retardation: –Extends working time from 30 minutes to several hours at low dosages (typically 0.001%–0.01% by weight of gypsum), with linear and predictable setting control.
Minimizing strength loss: –Unlike some organic acid retarders, it preserves or minimally affects the final mechanical strength of gypsum products.
Excellent compatibility: –Works with natural gypsum, flue-gas desulfurization (FGD) gypsum, phosphogypsum, and other gypsum types; compatible with cellulose ethers, redispersible polymer powders, and superplasticizers.
Easy handling & dilution: – Free-flowing water solution, easy dilution by water.
Stable & eco-friendly: –Formaldehyde-free, non-toxic, non-corrosive (chloride-free), and long shelf life.
🧱 Key Applications
Gypsum boards & blocks: – Optimizes production line speed, reduces breakage, and ensures consistent quality.
Decorative gypsum moldings: – Provides sufficient time for detailed filling, de-airing, and molding without rush.
